Abstract:Phospholipase D ( PLD) is the most p revalent enzyme in plant tissues that hydrolyzes phospholipids. PLD p lays important roles in cellular activities concerning from membrane biogenesis and degradation to signal transduction. Based on the authorspwork, this review focuses on PLD-catalyzed pathway of phospholipids in plants, the relationship between PLD and fruit development, senescence-related physiological and biochemical p rocesses by PLD, and gene cloning, expression patterns and protein structure of PLD. The role of PLD in fruit development and ripening was also discussed.
